Geranium Cultivar Sylvia's Surprise Continuous Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Geranium wallichianum that exhibits unique characteristics such as upright and spreading growth habit, continuous flowering, and pink-colored flowers, which differ from existing varieties like 'Buxton's Variety' and 'Rozanne' in terms of flower color and flowering frequency.
Innovation Solution
A naturally occurring mutation of Geranium wallichianum 'Buxton's Variety' resulting in the cultivar 'Sylvia's Surprise', characterized by its upright and spreading habit, vigorous growth, continuous flowering, pink flowers, and stability through asexual reproduction by tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a naturally occurring mutation is selected to create a new cultivar, then unique characteristics such as pink flower color and continuous flowering are achieved, but the stability of these traits must be verified through extensive asexual reproduction
Solution Approach 1:
The patent applies parameter changes by selecting a naturally occurring mutation that altered specific parameters of the parent plant, including flower color (from light blue to pink), flowering frequency (to continuous), and growth habit (to upright and spreading). These parameter changes create the unique characteristics that distinguish the new cultivar while maintaining genetic stability through asexual reproduction.
2Reliability
If the plant is propagated by tissue culture to ensure genetic stability, then true-to-type reproduction is achieved, but the propagation process requires controlled environmental conditions and time
Solution Approach 1:
The patent employs continuous asexual reproduction through tissue culture methods to maintain the genetic stability of the mutant traits. The controlled propagation process ensures that the unique characteristics (pink flowers, continuous flowering, upright habit) are consistently reproduced across generations, with rooting occurring in about 15 days and full plant production in about 45 days under controlled conditions.
